Bobg Posted April 4, 2012 Report Share Posted April 4, 2012 I'm going to be experimenting with a new glaze from John Hesselberth book and it calls for rutile. I get my supplies from the Clay Art Center in Seattle and they have two diifferent ones, one is milled ( thinking this is the one) and the other it says is "ceramic rutile", say's it should be screened before using due to various sized particles. I'm assuming that I need the milled rutile, but wanted to make sure. Thanks for the help. Bob Link to comment Share on other sites More sharing options...
Mark C. Posted April 4, 2012 Report Share Posted April 4, 2012 I buy Rutile in 50# bags-just checked bag and it does not say milled anywhere. It must be ceramic grade. I always screen my glazes anyway. Mark Link to comment Share on other sites More sharing options...
TJR Posted April 4, 2012 Report Share Posted April 4, 2012 You want the fine rutile-probably milled. You can also buy granular Rutile which is used to put "iron" spots in glazes when you fire in an electric kiln.It is a coaser grind and would have to be seived out if you want a smooth glaze TJR Link to comment Share on other sites More sharing options...
Mark C. Posted April 4, 2012 Report Share Posted April 4, 2012 I looked up my records-I get my rutile by the 50# bag from Laguna Clay Co. They sell 3 types Milled Ceramic Grade-which is plenty fine Granular –which looks sort of darkish I have been using ceramic grade for 30 years as I go thru lots The brands have changed over the years but its all been ceramic grade for me. I just check both my bags and they are really fine powder. Your supplier may have only two kinds Mark Link to comment Share on other sites More sharing options...
Bobg Posted April 5, 2012 Author Report Share Posted April 5, 2012 Thanks for the responses. I'm looking at making a smooth glaze so the milled would work the best. But, I've also been interested in adding to a glaze to add iron spots to it. I think I will buy the ceramic grade and screen it to take out the larger pieces to use later. Thanks again.

Bobg Bobg; I don't know if you are familiar with Dansk Pottery. They make a high end stoneware dinner plate in Albany slip colour[brown] and a white matt that has speckles. They are fired in oxidation in an electric kiln. [i think]. Potters add speckles to their glazes to get that stoneware reduction effect. You can use granular rutile, and you can also use granular illmanite. Don't quote me, but I think 2% would give you the effect you are looking for.I do not use these techniques in my own work, but remember them from art school.Good luck. TJR.
